I have to cover a 14 inch square cake with ombre fondant  ruffles....I've only attached fondant ruffles to a cake already covered in fondant...I'm tempted to try to attach the ruffles to buttercream but i'm a bit fearful that the ruffles will fall off...Any advice from past experience? TIA!!!

AI try this before whit no luck, for my daughter cake, save you self a headache and use fondant underneath, good luck ( maby the expert's have better look then I did)

AIf you build them from the bottom up you can attach the ruffles to each other so they don't collapse. HTH

Thank you for your advice and taking the time to help. I think I'm gonna stick with what I know and just cover it in fondant :) Thanks Again!!!

Thanks for the info, kisamarie. I have to make a tiered ombre ruffle cake for my best friend's daughter's wedding in June 2014. I've been debating fondant ruffles on buttercream (she doesn't like fondant) or making buttercream ruffles (I saw a great video on youtube). I want to make "test cakes" for a tasting for the bride and groom to see what they prefer and if fondant ruffles on buttercream even work! You rock!
